Causes ESLint error in host project development build

[krukid]

Steps to repro:

1. Install addon for your project with ember install ember-cli-workbox.
2. Ensure you have valid .eslintrc.js in project root.
3. Either run ember s or ember build.

Environment

• Docker image node:10-slim
• ember-cli@3.10.1
• ember-cli-eslint@5.1.0
• ember-source@3.10.1
• eslint@5.16.0
• eslint-plugin-ember@6.5.1
• broccoli-lint-eslint@5.0.0

Using Yarn workspaces: https://yarnpkg.com/en/docs/workspaces

Result:

Build Error (broccoli-persistent-filter:EslintValidationFilter) in app/instance-initializers/sw.js

No ESLint configuration found.

Workaround 1:

Disable hinting in your project's ember-cli-build.js:

app = new EmberApp(defaults, {
  hinting: false,
  ...
})

Workaround 2:

Add the following path to .eslintignore in project's root directory:

ember-cli-workbox/

PS

Production build works out of the box as it should.
